Plastics - Homopolymer and copolymer resins of vinyl chloride - Part 1: Designation system and basis for specifications (ISO 24024-1:2021)

1.1  This document establishes a system of designation for vinyl chloride thermoplastic resins which can be used as the basis for specifications.
1.2  The types of vinyl chloride plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties:
a)   reduced viscosity;
b)   apparent density;
c)   retention on a 63 µm mesh sieve;
d)   plasticizer absorption at room temperature (for general-purpose resins);
e)   the viscosity and the type of rheological behaviour of a standard paste (for paste resins only);
and on information about basic polymer parameters, polymerization processes and intended applications.
1.3  This document is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins can contain small amounts of non-polymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of polymerization.
1.4  It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they are determined in accordance with the test methods specified in ISO 24024-2, if suitable.
1.5  In order to specify a resin for a particular application or to ensure reproducible processing, additional requirements can be given in data block 5 (see 4.1).

1.1 Dieses Dokument legt ein System für die Bezeichnung von thermoplastischen Vinylchlorid-Polymeren fest, das als Basis für Spezifikationen angewendet werden kann.
1.2 Die Arten von Vinylchlorid-Polymeren werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften:
a) reduzierte Viskosität;
b) Schüttdichte;
c) Siebrückstand auf Drahtsiebboden mit 63 µm lichter Maschenweite;

1.3 Dieses Dokument ist anwendbar auf Polymere in Pulverform, die aus Homopolymeren des Monomers Vinylchlorid und Co- oder Terpolymeren usw. des Vinylchlorids mit einem oder mehreren Monomeren, in denen jedoch Vinylchlorid der Hauptbestandteil ist, bestehen. Die Polymere können geringe Mengen nicht polymerisierter Substanzen (z. B. Emulgatoren oder Suspensionshilfsmittel, Katalysatorreste usw.) und anderer während der Polymerisation zugesetzter Stoffe enthalten.
1.4 Es soll nicht unterstellt werden, dass Werkstoffe mit gleicher Bezeichnung notwendigerweise das Gleiche leisten. Dieses Dokument enthält keine technischen Daten, Leistungsangaben oder Angaben zu Verarbeitungsbedingungen, die notwendig sein können, um einen Werkstoff für eine bestimmte Anwendung und/oder Verarbeitungsart zu spezifizieren.
Wenn derartige zusätzliche Eigenschaften erforderlich sind, werden sie nach den in ISO 24024 2 festgelegten Prüfverfahren, sofern geeignet, bestimmt.

1.1    Le présent document établit un système de désignation des résines thermoplastiques à base de chlorure de vinyle, qui peut être utilisé comme base pour les spécifications.
1.2    Les types de plastiques à base de chlorure de vinyle sont différenciés les uns des autres par un système de classification basé sur les niveaux appropriés des propriétés de désignation suivantes:

Overview

EN ISO 24024-1:2021 (CEN adoption of ISO 24024-1:2021) defines a standardized designation system and basis for specifications for vinyl chloride thermoplastic resins (PVC homopolymers and copolymers) in powder form. The standard establishes how resins are identified and classified for use as the basis of technical specifications, while clarifying that identical designations do not guarantee identical performance or processing behaviour.

Key topics and technical requirements

• Scope and applicability: Applies to powder resins where vinyl chloride is the main constituent (homopolymers, copolymers, terpolymers). Small amounts of non‑polymerized reagents or polymerization additives are permitted.
• Designation format: A standardized pattern consisting of an optional Description block, an Identity block (International Standard number) and an Individual‑item block subdivided into five data blocks (1–5). Data blocks are separated by commas; unused blocks are shown by two commas.
• Data block 1 (Identification):
  • Resin symbol: PVC for homopolymer or VC/.../... for copolymers/terpolymers (per ISO 1043‑1).
  • Provides combined vinyl chloride content (calculated from chloride content as specified in the standard) and polymerization process codes: S (suspension), E (emulsion), M (bulk), X (other/intermediate).
• Data block 3 (Intended application): Codes for Paste (P), Filler (F), or General‑purpose (G).
• Data block 4 (Designatory properties): Encodes key properties used for classification:
  • Reduced viscosity (three‑figure code)
  • Apparent density (two‑figure code)
  • Retention on a 63 µm mesh sieve (two‑figure code)
  • Plasticizer absorption at room temperature (two‑figure code - for general‑purpose and filler resins)
  • Paste resins: paste formulation letter, viscosities at specified shear times, and rheological behaviour code
• Limitations: The standard does not provide engineering, performance or processing conditions; additional testing and properties are specified in ISO 24024‑2 when required. Data block 5 can hold extra requirements for specific applications.

Practical applications

• Creating unambiguous material designations for procurement documents and specifications.
• Classifying PVC resins for quality control, inventory, and supplier communication.
• Supporting regulatory filings, material declarations and traceability across supply chains.
• Assisting R&D and formulation teams to select resin types (paste, filler, general‑purpose) based on standardized property codes.

Who should use this standard

• PVC resin manufacturers and suppliers
• Material specifiers, formulators and compounders
• Quality assurance and procurement teams in plastics processing industries
• Standards committees and conformity assessment bodies

Related standards

• ISO 24024‑2 - Test methods and sample preparation (referenced for additional property determination)
• ISO 1043‑1 - Symbols and abbreviated terms for basic polymers
• Supersedes ISO 1060‑1:1998; adopted as EN ISO 24024‑1:2021 by CEN

Keywords: EN ISO 24024-1:2021, PVC designation system, vinyl chloride resins, reduced viscosity, apparent density, 63 µm sieve retention, plasticizer absorption, paste resin classification.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
